Abstract

An extensive review of multi-seam under-mining literature was conducted and a data base of case studies was compiled. A critical review of the design principles outlined in this literature resulted in the compilation of specific design criteria for the design of lower seam mines. Analysis of this criteria demonstrated the necessity for a protocol for the design of unsymmetrically loaded pillars. Such a design criteria was developed using finite element methods for a wide range of possible loading conditions. This design criteria can be utilized for underlying pillar design when the loading conditions can be determined. To facilitate using all the under-mining research results by field/planning engineers a Windows™ based software package was developed. This software package contains a multi-seam tutorial, analytical tools and a case history database. The software is very friendly and fully interactive and results of analysis can be verified against case study data included in the program.
